CONVEYER.

My invention relates to conveyers and the principal object of my invention is to provide a new and improved conveyer. In the drawings accompanying this specification and forming a part thereof I' have shown, for purposes of illustration, one form which my invention may assume. In these drawings:

Figure 1 represents a plan vievs7 of this illustrative conveyer, While Figure 2 represents a side View of the conveyer shown in Figure 1.

The conveyer herein illustrated is designed to carry strips of fabric from the conveyer belt of a bias cutter. In order to simplify the drawings and to prevent confusion I have not shown the bias cutter but have merely indicated in Figure 1 the center line of the co-operating bias cutter.

The conveyer herein illustrated comprises a frame 11 provided With a standard 12 havingbearings 13 in which is mounted a shaft 14 Which carries a pair of pulleys 15, serves as a bearing for a drum 16, and is operated r by means of a gear 17 which is in turn driven by a sector 18 pivoted at 19 to the frame 11 and in turn operated by the link 20 pivotally secured at 21 to a block 22 which is slidable in Ways 23 on the sector 18 and controlled in position by the screw 24 to thereby control the degree of movement imparted to the sector by a constant stroke of the link 20. This link 20 is provided with a. roller 25 operating in a groove 26 of cam Wheel 27 which is in turn pivote-d at 28 and operated in any suitable manner. rIhe link 2O is restrained in movement by a bearing 29 pivoted at 30 to an arm of a block 31 secured to the base 11. The drum 16 is lconnected to the pulleys 15 by a clutch (not shown) which causes the drum to rotate with the pulleys in one direction but to remain idle during the reverse rotation of the pulleys. The uprights 12 are also provided with a pair of bearings 32 Which'support a roller 33 and with a pair of spindles 34 each of which supports a pulley 35. The base 11 also carries a second pair of uprights 36 Which are provided With bearings 37 each of which supports a pulley 38. Suita-bly supported beneath the conveying belt of the bias cutter is a table 89.

Extending on each side of the conveyer from the ends of a Heating drum about the pulleys 38 to the ends of a second floating drum 41 are a pair of cables 42 and con-l tinuing from the ends of the lower drum 41 about the pulleys 15 back to the ends of the upper floating drum 40 are a pair of cables 45. Extending from the main drum 16 out over the upper floating drum 40 thence around the drum 33 then out around the lower floating drum 41 and back to the main drum 16 is the'conveyer belt 44.

In operation the conveyer is initially in the position shown in Figure 2 and the stri 3s to be carried away are being brought to t e conveyer on the belt of the bias cutter which passes over the table 39 and advances periodically. 4s a strip is deposited opposite the conveyer t-he conveyer is set in operation. This operation causes clockwise rotation of the pulleys 15 to thereby act through the cables 42 and 43 to draw the upper floating drum 40 to the right and the lower floating drum 41 to the left. rIhis movement of the pulleys 15 does not operate the drum 16 and accordingly the belt 44 is relatively stationary and the necessary elongation of the upper pass 45 of the belt 44 and shortening of the lower pass 46 thereof is accomplished by movement of the belt about the drums 41, 33, and 40. As the forward movement of the drum 40 begins the adjacent end of the strip of material is attached by overlapping to the rear end of the previous strip hanging from the belt 44 at the drum 40 and accordingly continued advance of the drum 40 with the coincident movement of the belt 44 around the drum 40 will cause the belt 44 to continuously pick up the strip until at the completion of the advance movement of the drum 40 substantially the entire strip is resting upon the upper pass 45 of the belt 44. Further operation of the conveyer then causes reverse movement of the pulleys 15 and this reverse movement actuates the drum 16 to thereby cause the belt 44 to travel bodily in a general counterclockwvise direction to thereby carry away the strip. It Will be obvious that this cycle of operations may be repeated indelinitely and will result in a continuous strip being delivered by the belt 44 to the subsequent handling device.

The description herein is illustrative only and many modifications and alterations are possible and my invention is, of course, not limited to this disclosure.

I claim:

l. Conveyinv mechanism comprising two relatively iixed pulleys, a belt passing over said pulleys, two relatively movable pulleys positioned beyond the ixed pulleys and adapted to form loops in the upper and lower runs of the belt, means to simultaneously reciprocate the movable pulleys in opposite directions, a table in the path of the upper loop and means to move the upper run of the latter as the upper loop recedes 'from the table.

2. Conveyer mechanism comprising two relatively fixed pulleys, a belt passing over sai-d pulleys, two relatively movable pulleys positioned beyond the fixed pulleys and adapted to form loops in the upper and lower runs of the belt, means to simultaneously reciprocate the movable pulleys in opposite directions, a table in the path of the ripper loop and driving means for the belt adapted to maintain the belt relatively stationary as the upper loop advances toward and over the table and to advance the belt in the direction of the movement of the upper loop as the latter recedes from the table.

In testimony whereof I have signed my name to the above specification.
